The abbreviation cf. stands for the Latin word confer which means âcompare.â It is primarily used in endnotes or footnotes to point the reader to works that offer an argument which contradicts or is otherwise different from the authorâs argument.he abbreviation i.e. stands for id est, which translates literally as âthat is.â Sometimes it might be more useful, however, to translate it as âwhat that means isâ or âthat is to say.â This abbreviation is used to clarify the preceding idea by restating it more simply or in different terms.
